Industry-Leading Data Acquisition Systems

Why choose ESC Spectrum for your plant’s Data Acquisition System (DAS) needs? We provide end-to-end solutions that include products and services custom-built for every part of the air emissions compliance and monitoring process. Our Data Acquisition Systems are in constant development and supported by in-house professional DAS services and a 24/7 customer support team.

StackVision is a user-configurable DAS, not a programmed solution. After our Implementation Team completes setup, security-enabled users can view and edit their configurations, calculations, exceedance limits, alarms and new parameters to be monitored — all without knowledge of
programming languages.

Prism allows facilities to easily capture, analyze, calculate, and report emissions data for federal, state and local environmental compliance. It is a scalable DAS software solution that can operate in stand-alone and enterprise environments and ensures users meet regulatory reporting requirements for emissions. Prism operates on Microsoft’s Windows and SQL Server.


Air Emissions Management Software

Air emissions software for compliance from ESC Spectrum helps simplify your ability to meet regulatory requirements. As part of our complete suite of Continuous Emissions Monitoring System (CEMS) solutions, ESC Spectrum’s air emissions management software includes:

FleXReports is subscription-based software that helps facilities easily and securely export data from StackVision into Microsoft Excel for maximum flexibility. Users have the power to develop fleetwide reports that aggregate data, then customize the format using familiar Excel functionality.

QAInsight serves as a single source for QA test data and ensures data consistency and organization by eliminating errors and lack of inter-departmental communication associated with the use of spreadsheets and other manual methods.

Run schedule-based status reports by facility or task type for different departments easily. Configure email notifications to send notices to staff about upcoming current and past due deadlines.

RATAView software helps stack testers perform Relative Accuracy Test Audits (RATA) tests accurately and efficiently to meet complex regulations, including requirements around testing frequency, calculations, data gathering, and data retention. This software is configurable to meet your needs and easy to implement – you can run it from a standard workstation PC.
